Title: Constant pressure printing mechanism for hand labeler
Inventor: SATO YO
Filed: 1978-02-28
Granted: 1982-10-12
Abstract: The actuating lever(3) is divided into a hand lever(4a) & a printing lever(46), which are pivotally connected to each other.  A printing head(9) is carried by the printing lever with a shock-absorbing tensioned spring(20) interposed between the hand lever & the printing lever.  This causes them to rotate toward each other & to rotate the printing head toward the platen(23).  A retaining lever(17) is engageable with the printing platen upon descent of the printing lever.  The retaining lever allows the hand lever to pivot slightly against the biasing force of the tension spring, even when the printing head abuts against the platen.  Thus the shock can be absorbed to ensure printing preformed under a const. press.

Title: Circuit for allocating access to a demandshared bus
Inventor: DIMMICKM JAMES O
IPC: G06F13/374
Filed: 1983-01-07
Granted: 1988-07-02
Abstract: The circuit for access allocatin to a number of demanding terminals is carried out for a shared collecting line in a priority determining process.  Each demanding terminal remains in the demand competition only as long as each of its digits is higher than those of another terminal.  After application of all digits only the terminal with the highest code remains in contention and engages the line.  On application of a reversing signal to this core for a certain time period, each demanding terminal inverts each bit of its priority code applied during this period to the collecting line.  The polarity core enables a change of normal hierarchy of the terminals.
